# Activate SSO

Yes, it is possible, but note that GLPI Network Cloud offer does not allow compatibility between following tools:

* basic Apache authentication;
* Windows domain authentication.

You can use the following tools:

Authentication server like LemonLDAP NG, Shibboleth, etc;

* CAS;
* X509 certificate;
* oAuth (with oAuth plugin).

You can configure your authentication in the **`Setup`** > **`authentication`** menu.

For authentication via oAuth, make sure that oAuth plugin is installed and activated on your instance in **`setup`** > **`plugins`**.

Access the plugin's configuration by clicking on it or by **`setup`** > **`Oauth SSO applications`**

To setup oAuth authentication, follow this [article](https://glpi-plugins.readthedocs.io/en/latest/oauthsso/index.html)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.glpi-project.org/tutorials/authentication/activate_sso.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
